It's a mixed bag, to my taste. On the one hand, the game's concept gives a lot of immersion, which is very important for an NTR game. On the other, build-up is lacking, and each route is quite short, even those that feel mostly complete. The game's strongest point - the phone simulation - also limits it to lack of scenes, which shouldn't actually be the case at all. No one stops the author from adding actual sex scenes with CGs outside of the phone, and just your normal VN interactions. Like, I want to see the MC interacting with the girl when she comes to his place, don't just read chat message and a screen. The same goes for NTR scenes.
I don't know if those are just technical limitations, but I doubt it. Having phone conversations shouldn't be the entire game, but rather a gimmick which adds to other aspects of the game. Though I think the creator promised at least one "video" for the gal girl.
Adding "outside of the phone" scenes would pretty much solve most of the game's problems.
p.s. The "scene" where the MC gets beaten up by the black guy is so dumb, btw, I mean just go to the fucking police and ruin his life if you got beaten up. Dude assaulted you at your home, that's some serious fucking charges that could put him in prison where his bbc won't save his ass. The game allows you to dump girls, but where the heck are the revenge options? On another note, no author, AI ART isn't immoral or evil, get off your high horse. "Oh no, I spent my entire life learning how to ride a horse, it's so unfair that people invented cars, it's immoral."
